Siemens SENTRON Series Nh Fuse, 630A Current, 690V Voltage - 3ND1372

This NH fuse is a low-voltage high-rupture-capacity fuse link designed for AC and DC switchgear applications. It provides a protective aM characteristic for mixed load circuits and incorporates front indicators with blade contacts and non-corroding silver-plated switching contacts. The device is intended for use where a high breaking capacity and clear status indication are required in industrial electrical installations.

Features and Benefits:

• 120kA breaking capacity enables safe fault interruption
• 50W power loss reduces thermal stress during operation
• IP20 protection class guards against solid-object ingress
• Non-corroding silver-plated contacts ensure consistent conductivity
• Front indicators provide visible fuse status for Rapid checks

Applications

• Suitable for industrial switchgear protection in factories
• Used with mixed motor and cable circuits requiring aM protection
• Ideal for AC and DC distribution boards up to 690V
• Can be used in environments with up to 95% relative humidity
• Suitable for installations needing non-insulated grip lug mounting

What ambient temperatures can it operate within?

It operates between -5°C and 40°C during service.

How is the fuse mounted in distribution systems?

It is fitted using non-insulated grip lugs and blade contacts for straightforward insertion.

What is the expected power dissipation at rated current?

At rated current it dissipates 50W per pole in the hot operating state.

How does the device indicate fuse operation?

It uses front-mounted Visual indicators to show operating condition.

What environmental category ratings apply to storage and operation?

Operation is specified for -20 to +50°C at 95% relative humidity and storage at 90% relative humidity at 20°C.
